Topic: Extruder motor "Ticking"

Just started hearing a weird ticking on my SD3.  Finally figured out it was the extruder motor.  What causes this and how is it fixed?

Just really bugged by the sound.

Re: Extruder motor "Ticking"

Does it make the same sound when in manual control just extruding?

I had the same problem today with my SD3. I loosened the tightening screw and it went away. Let us know if this does not work.

Which screw?

Re: Extruder motor "Ticking"

I loosened the tensioning screw on the extruder. The one that grips the filament. I don't like it to mark the filament. I think, in my case, this was what was causing the ticking noise.

Another take on this issue: Have you loaded new firmware?

I was just experimenting with making sure I could load and restore the firmware, and found that with the new Marlin beta firmware loaded, printing a test cube make the extruder start clacking when it retracted at the corner. Putting back the original firmware then made it even worse till I also put back the original eeprom, then the test cube was perfect again and all clacking noises stopped:

Re: Extruder motor "Ticking"

Didn't have problems with the ticking sound until I moved the unit from a windows 7 machine to a mac 10.6 machine.  Lots of weird things are happening when using the mac.

Re: Extruder motor "Ticking"

Loosening the tension screw is a bad idea as the filament can just be stripped. If it is just ticking on occasion you may just need to reduce your flow multiplier. I had that problem too.
